For the first time since 1959 a big boy makes a trip over Sherman Hill on its own without diesels I think the King will be quite capable of pulling a passenger car as they were designed to haul freight trains on this line
-
Can actually hear it truly working for the first time. 🙌🔥
-
15 hoppers, piece of cake for a Big Boy
-
The diesel engine was used for dynamic braking and positive train control. They now have figured out how to put ptc on the steam engine.
-
I would love to be in that cab tho Hearing it work in person is probably very astounding
-
impressive for her backing up!
-
What a magnificent machine. I wonder what qualifications an engineer needed to be assigned a Big Boy back in the day.
-
TOTALLY AWESOME LOCOMOTIVE!
-
#4014 was making history.
-
Could I use some of the footage? It's been DECKADES since we saw this guy without a Diesel.
-
Just repeating history from 3985 pulling 143 cars…
-
looking for wheel slip
-
I thought big boy only needed helpers to supply electricity to power the coaches and maybe some dynamic breaking
-
I doubt the diesel is an assistant. This steamer burns 35 you fuel and uses perhaps 300 gallons of water per mile . A good fire and mucho power. The diesel is there for a breakdown if it happens to get the train off the main line, eh?
-
Ok so why the modern locomotive in with the rest of this short train ?
-
Big Boy take good job without diesel helper but I notice she work hardly for acceleration the train and emiss a lot of smoke.
-
UP 4014 had breaks in 1941 and pulled way more than 14 cars😂. UP has shamed every engineer & fireman who ever took this beast on back in the day. Drop the diesel! Not needed
-
Loose coupling rods
-
Our Big Boy has problems running without the diesel, delivering all that EV fuel...
